Unit Of competency

Modification History

Release 1. Supersedes and is equivalent to PMASUP246A Disconnect and reconnect non-flared tube fitting joints

Application

This unit of competency covers the skills and knowledge required to disconnect and reconnect non-flared tube fitting joints using hand tools.

This unit of competency applies to operators who are required to identify requirements for the work, ensure they are working within their skill level, confirm isolations are in place, apply procedures to disconnect and connect tube fitting joints, undertake checks and inspections, complete records, and identify problems and take appropriate action.

This unit of competency applies to an individual working alone or as part of a team or group and working in liaison with other shift team members and the control room operator, as appropriate.

This unit does not cover the initial installation of tube fittings, high pressure fittings or cone fittings.

No licensing, legislative or certification requirements apply to this unit at the time of publication.

Assessment requirements

Modification History

Release 1. Supersedes and is equivalent to PMASUP246A Disconnect and reconnect non-flared tube fitting joints

Performance Evidence

Evidence required to demonstrate competence in this unit must be relevant to and satisfy the requirements of the elements and performance criteria, and include the ability to:

  • replace existing components with new components
  • carry out minor maintenance within own skill level
  • identify and report problems outside own competence
  • identify and control hazards related to tube fitting joints
  • inspect job site to confirm:
  • location
  • authorisations required
  • access and egress needs
  • recent work undertaken on joint
  • tube fitting type matches specification
  • inspect non-flared tube fitting components to check for:
  • contaminants
  • signs of damage, defects or deterioration in all components
  • cleanliness and correct surface roughness of mating surfaces
  • alignment
  • correct specifications.

Knowledge Evidence

Evidence must be provided that demonstrates knowledge of:

  • tube connection types as applicable
  • principles of how non-flared tube joints seal
  • tool types and applications
  • organisation’s tube fitting procedures
  • hierarchy of control
  • communication protocols (e.g. radio, phone, computer, paper and permissions/authorities)
  • routine problems, faults and their symptoms, and the corrective action to be taken
  • process materials and conditions at the location of the fitting
  • relevant environmental requirements.

Assessment Conditions

  • The unit should be assessed holistically and the judgement of competence based on a holistic assessment of the evidence.
  • The collection of performance evidence:
  • should occur over a range of situations which include typical disruptions to normal, smooth operation of an operating plant
  • will typically include a supervisor/third-party report focusing on consistent performance and problem recognition and solving. A supervisor/third-party report must be prepared by someone who has a direct, relevant, current relationship with the person being assessed and who is in a position to form a judgement on workplace performance relevant to the unit of competency
  • must include the disconnecting and reconnecting of at least two (2) non-flared tube fitting joints, the use of appropriate tools, equipment and safety gear requiring demonstration of preparation, operation, completion and responding to problems
  • may use industry-based simulation for all or part of the unit particularly where safety, lack of opportunity or significant cost is an issue.
  • Assessment should occur in operational workplace situations. Where this is not possible, or where personal safety or environmental damage are limiting factors, assessment must occur in a sufficiently rigorous simulated environment reflecting realistic operational workplace conditions. This must cover all aspects of workplace performance, including environment, task skills, task management skills, contingency management skills and job role environment skills.
  • Assessment in a simulated environment should use evidence collected from one or more of:
  • walk-throughs
  • pilot plant operation
  • demonstration of skills
  • industry based case studies/scenarios
  • ‘what ifs’.
  • Knowledge evidence may be collected concurrently with performance evidence (provided a record is kept) or through an independent process, such as workbooks, written assessments or interviews (provided a record is kept).
  • Assessment processes and techniques must be appropriate to the language, literacy and numeracy requirements of the work being performed and the needs of the candidate.
  • Conditions for assessment must include access to all tools, equipment, materials and documentation required, including relevant workplace procedures, product and manufacturing specifications associated with this unit.
  • The regulatory framework will be reflected in workplace policies and procedures and is not required to be independently assessed.
  • Foundation skills are integral to competent performance of the unit and should not be assessed separately.
  • Assessors must satisfy the assessor competency requirements that are in place at the time of the assessment as set by the VET regulator.
  • In addition, the assessor or anyone acting in subject matter expert role in assessment must demonstrate both technical competency and currency. If the assessor cannot demonstrate technical competency and currency they must assess with a subject matter expert who does meet these requirements.
  • Technical competence can be demonstrated through one or more of:
  • relevant VET or other qualification/Statement of Attainment
  • appropriate workplace experience undertaking the type of work being assessed under routine and non-routine conditions
  • appropriate workplace experience supervising/evaluating the type of work being assessed under routine and non-routine conditions
  • Currency can be demonstrated through one or more of:
  • being currently employed undertaking the type of work being assessed
  • being employed by the organisation undertaking the type of work being assessed and having maintained currency in accordance with that organisation’s policies and procedures
  • having consulted/had contact with an organisation undertaking the type of work being assessed within the last twelve months, the consultation/contact being related to assessment
  • conducting on-the-job training/assessments of the type of work being assessed
  • being an active member of a relevant professional body and participating in activities relevant to the assessment of this type of work.
